Abstract

Time reversal (TR) backpropagates a signal to its origin despite the complexity of the propagation channel. The application of TR to acoustic communications previously has been demonstrated. Here, we discuss the advantages of an implementation of the TR process cascaded with adaptive channel equalization. This combination makes spatial diversity unnecessary in the receiver structure. In addition, comparisons will be drawn between single source and TR transmissions in combination with adaptive channel equalization. [Work supported by ONR.]
